TROLLEY-WHEEL.

SPECIFICATION forming part of Letters Patent No. 630,210, dated August1, 1899.

Application filed June 30, 1897. Serial No. 642.920. (No model.)

To all whom, it nur/y cancel-71,:

Be it known that I, HENRY R. FRIsBIE, a citizen of the United States,and a resident of Belleville, in the county of Essex and State of NewJersey, haveinvented certain new and useful Improvements inTrolley-Wheels, of which the following is a specifioation.

My invention relates to trolley-wheels, and particularly to that classwhich operate as secondary conductors in the overhead electrical trolleysystem for street-railways.

The object of myinvention is to so constru ct a trolley-wheel that itwill be self-lubricatin g and easily repaired. To this end the wheel isconstructed of three parts, the center or conductor proper being made ofcopper or other suitable conducting material, while the two sides of thewheel are made of a cheaper, harder, and inferior grade of metal, sothat such sides will outlast many of the centers.

It further consists in forming a Chamber around the center for holdinglubricatin g material, like graphite, which will work through holesprovided in the bore of the wheel onto the spindle or pin on which suchwheels run.

To enable others to understand my invention, reference is had to theaccompanying drawings, in which- Figure 1 represents a side elevation ofmy completed wheel. Fig. 2 isa central sectional view through line a ofFig. 1. Fig. 3 is a detail side elevation of the detachable centralportion of the trolley-wheel. Fig. 4E is a detail central sectional viewof the sides or flanges. Fig. 5 is a detail sectional view of the hub ofthe central portion of the wheel through line b of Fig. 2. Fig. 6 is adetail broken view, partly in section, of a modified form of attachingthe sides or flanges to the central hub.

Its construction and Operation are as folloWs:

1 is the central or tread portion of the wheel, made of copper, bronze,or other suitable conducting material.

1 is a hub portion having the bore 2 to serve as a bearing for the usualpin or stud. (Not shown.)

3 and 3 are the side flanges, attached to the detachable center by meansof the bolts 4, passing through the openings 5 of the web portion ofsuch center. The interveniug space between the said flanges and the hub1 forms a chamber for the loose graphite 6. 7

are longitudinal grooves in the inner walls of 5 5 the bores of the hubof the ilanges, so as to dispense with the bolts, as shown at Fig. 6, inwhich the openings, Fig. 3, would still be retained to permit thegraphite to have free access to both sides of the secondary conductor orcenter 1,while the holes 10 in the fianges would not in this case beformed.

11, Fig. 4, is a recess formed in the face of each of the side flangesto admit the circular ribs 12 on the vertical face of the center 1, asshown at Fig. 2. terially in locating the said fianges thereon.

The improved trolley-wheel as above de scribed is far more economicalthan a solid wheel, as the cost of the interior metal of which thesideflanges are made is much lower 8'o than the center, which operates asthe conductor, which center will wear out faster than the flanges,whereupon the said center is quickly removed and a new one put in itsplace. are made entirely of copper or bronze, as is now the case,thewhole wheel has to be thrown away. The Chamber for the lubricant issufficiently large to hold more than enough graphite to outlast anysingle center, so that 90 when the wheel is put together it will need nofurther attention until the center has become so far reduced in size asto require another.

Having thus described my invention, what I claim as new, and desire tosecure by Letters 95 Patent, is-

A sectional trolley-wheel consistingof a renewable center having a rim Ushape in cross-section a grooved periphery to form the contact, said rimmade deeper in its central Ioo portion to enhance its wearing qualitiesand thcreby prolong its usefulness,a hub on which The said fianges 3 and3*- are each 60 This feature will assist ma- On the other hand, wherethe wheels side fianges are supported, a thin central Web ohambers,means for uniting and holding the connecting said hub With said ri'm sothat several sections together, substantiallyasdewhen the flanges aremounted on said hub scribed and'for the purpose set forth. side chambersare formed for loose graphite Signed at Bridgeport, in the County ofFair- 5 or other like powdered lubricant, large openfield and State ofConnecticut, this 28th day 15 ings in said web to open communicationbeof June, A.
